[PD] Raspberry Pi versus BeagleBoard ?

[Alexandros Drymonitis]

Yup, I'm using their distro as I got it from them at the workshop. Not sure
which version it is, the workshop took place last June, so it shouldn't be
old...
Building a stombox out of a machine as powerful as a smart phone...dunno.
Edgar Berahl himself said that the BB is as powerful as an iPhone 4, or
something. How much could it take?...And we did have some CPU issues during
the workshop, especially with [expr~]..
